About

My work bridges Machine Learning, Network Science, and Data Science, with a strong emphasis on human-centric, trustworthy AI. I design and deploy methodologies that advance explainability, fairness, and transparency, translating research into accountable systems aligned with societal values.

I lead industrial collaborations bringing generative AI to high-stakes domains such as legal document analysis and anti-financial-crime compliance, pairing technical innovation with regulatory alignment. I also serve as PI of the EU-funded PRE-ACT consortium—running a Phase III trial on AI-assisted breast radiotherapy decisions—building bias-aware evaluation pipelines and practical guidelines for Fair, Transparent & Ethical AI.

Over 15+ years I've contributed to both foundational research and scalable systems in complex socio-technical settings, including real-time data pipelines and graph-based learning for behavior modeling and risk detection. My research spans graph neural networks, XAI, and LLM-powered document analysis (RAG), with publications at NeurIPS, KDD, TKDE, TMLR, and WWW.
